Brovin Kacher

[d3x0r]

I found that shifting the primary on the secondary can dramatically improve output; such that there is a exact match in frequencies. 
I've moved my ground a few times; and maybe that's what the issue is now... it was working good   now it's all high current and no output....


this one part tests correctly; but it's like the internals are broken so that almost any gate voltage more than zero opens it.... (maybe it's the ground; sometimes it's just that I need to tell someone what I was doing)


I have these 3 coils that all oscillate together so I can light a flouresent at each one, but not between with only a ground connecion; was going to dig up that current transformer thing and try it between the coil and ground and see... oh and to connect top to top? and the second side is open?

Nice thread John,

i wanted to do some experiments with 2 Kacher coils driven by 1 primary for some time and i guess this thread is right for this.

In the back of my mind the following website and the below diagram plays a role allthough i am aware its very different.

http://www.bibliotecapleyades.net/tesla/esp_tesla_20.htm

Both kachers are running kind of, and there is some interaction as the streamers are mingling.

Need to set up the glas inbetween with a fixture so its more stable, and also a conductive groundplain underneath the 2 coils could improve the interaction.

Anyway, here the first video: https://www.youtube.com/watch?v=8xAmeFA-L2U&feature=youtu.be

Hi Itsu, some fine experiment you running. No fire balls yet ? What about to try top capacitors with the charge breaker? I woud wrap the bulbs in kitchen foil and a piece of wire. Looking forward to see more on your chanel.

Regarding having one primary for two secondaries, you may also be interested in this guy's videos.
He is not using tesla coils, but self wound transformers (his last video uses an air core  transformer) but
his approach should be applicable for use with kacher driver circuits. I believe he is testing with both phase
opposing secondaries, and also with phase opposing primary windings. He calls his transformer a 'free energy' transformer,
but he actually doesn't have the equipment to do proper power measurements. What his videos show
is that adding a light bulb load does not increase the input current to the primary. That doesn't say anything about
over unity of course, but it is still interesting. He doesn't have a scope to look at the phase relationship between the
primary voltage and the primary current, and I would guess that when he connects the light bulb load that the
input phase is shifting, increasing the input real power consumption. A person would need a scope to confirm. Anyway, this approach
could probably be adapted to a kacher-brovina driver. Read the description section for his videos. He has English descriptions of what
he is doing in the videos.

Nice Unfortunatly I noticed the article was talking about MegaVolts... so he's already expecting to start with a HV supply with a spark gap instead...


but those are quite lively ends on your coils
